A connecting portion is provided, and the fixed connecting portion is provided with fixing portions fixed to the housing on both end sides thereof, and includes a conductive plate-like first plate-like body and the flexible conductive material. A second plate-shaped body connected and having conductivity is provided, the second plate-shaped body having a length in a longitudinal direction shorter than that of the first plate-shaped body, and fixed to the housing. The first plate-like body and the second plate-like body are laminated in the plate thickness direction, and the fixing portion of one of the first plate-like bodies and the fixing portion of the second plate-like body are overlapped and fixed to the housing, and the fixing portion on the other side of the first plate-like body and the wire-side terminal are overlapped and fixed to the housing. characterized by

Further, according to the present invention, there is provided an electric wire with a connector, which includes the connector described above and the electric wire having the electric wire-side terminal attached to the tip thereof, and the connector is arranged at the tip of the electric wire.
The terminals of the mating connector are terminals provided in or connected to equipment such as electrical equipment and power supply equipment.

These inventions make it possible to absorb the influence of external force and improve the assembling property.
Specifically, a flexible conductive member connected to the terminal fitting and a fixed connection portion connected to the wire-side terminal and the flexible conductive member and fixed to the housing are provided inside the housing. and the fixed connection portion includes a first plate-like body having fixing portions fixed to the housing provided on both end sides thereof, and a second plate-like body to which the flexible conductive material is connected. The second plate-like body is formed to have a length in the longitudinal direction shorter than that of the first plate-like body. That is, the flexible conductive material connected to the terminal fitting is connected to the second plate-like body having a shorter length in the longitudinal direction than the first plate-like body. Therefore, the flexible conductive member connected to the terminal fitting and the second plate-like body can be easily assembled to the housing.

A fixing portion fixed to the housing is provided on one of both end sides of the second plate-shaped body, and the first plate-shaped body and the second plate-shaped body are laminated in the plate thickness direction. At the same time, one of the fixing portions of the first plate-like body and the fixing portion of the second plate-like body are overlapped and fixed to the housing. Therefore, the flexible conductive member connected to the terminal fitting can be fixed to the housing separately from the wire-side terminal connected via the fixed connection portion.

Furthermore, since the fixing portion on the other side of the first plate-like body and the wire-side terminal are superimposed and fixed to the housing, the flexible conductive member is separated from the flexible conductive member connected to the terminal fitting. , the wire-side terminal can be fixed to the housing, the flexible conductive material connected to the terminal fitting via the first plate-like body and the second plate-like body; terminals can be electrically connected.

In this manner, the terminal fitting and the flexible conductive member can be attached to and assembled with the housing independently of the wire-side terminal, and the wire-side terminal can be attached to the terminal fitting and the flexible member. It can be attached and assembled to the housing independently of the flexible conductive material. Therefore, the terminal fitting, the flexible conductive material, and the wire-side terminal can be easily mounted and assembled in the housing, and electrically connected via the first plate-like body. Therefore, the flexible conductive material can absorb the influence of the external force, and the terminal fitting, the flexible conductive material, and the wire-side terminal can be easily assembled to improve the assembling property of the connector. can.
Moreover, since the first plate-like body can be fixed to the housing by the fixing portions on both ends, a stable connection state can be maintained.

As an aspect of the present invention, one of the fixing portions of the first plate-like body, which is fixed to the housing by overlapping the fixing portion of the second plate-like body, is arranged on the side away from the electric wire. may
According to the present invention, since the other fixing portion of the first plate-like body and the wire-side terminal can be overlapped and fixed to the housing, the wiring route of the plate-like body and the flexible conductive material becomes complicated. can be suppressed, and the connector can be configured compactly.

According to this invention, the flexible conductive material can be reliably connected to the second plate-like body. Further, the housing often expands and contracts due to heat along the direction in which the terminal fittings are arranged. An external force due to expansion/contraction or the like acts on the connecting portion of the flexible conductive material connected to the surface. As a result, the connection between the second plate-like body and the flexible conductive material may become unstable. On the other hand, since the main surface to which the flexible conductive member is connected is arranged in a direction intersecting the arrangement direction of the terminal fittings, connection of the flexible conductive member connected to the main surface is difficult. External force due to expansion/contraction or the like is less likely to act on the portion, and a stable connection state can be maintained.

Further, as an aspect of the present invention, the second plate-like body may be laminated on the side of the first plate-like body away from the terminal fitting.
According to the present invention, the flexible conductive material connected to the terminal fitting is connected to the second plate-like body so as to wrap around the fixed connection portion, so that the first plate-like body is Compared to the case where the second plate-shaped body is arranged on the terminal metal fitting side, the deformation allowance following the expansion and contraction of the housing due to heat is increased, and the flexibility is increased when the housing expands and contracts. The conductive material is compactly deformed. Therefore, the connector can be configured compactly.

Moreover, as an aspect of this invention, the said fixing|fixed part may be fastened and fixed with a fastening member with respect to the said housing.
According to the present invention, the first plate-like body and the wire-side terminal, and the second plate-like body and the first plate-like body are superimposed and fastened with a fastening member so that they can be firmly fixed to the housing. can.

A wire-side connector 20 having a terminal holding portion 21 and a wire harness 200 having the wire-side connector 20 at its tip are connected to a female terminal 31 inside the terminal holding portion 21 to provide flexibility. and a connection fixing member 34 connected to the wire-side terminal 33 and the flexible conductive member 32 and fixed to the terminal holding portion 21. The connection fixing member 34 is connected to the terminal Through holes 351 fixed to the holding portion 21 are provided on both end sides, and the conductive plate-shaped first bus bar 35 and the flexible conductive material 32 are connected to each other. The second bus bar 36 is shorter in the longitudinal direction than the first bus bar 35, and has a through hole 361 fixed to the terminal holding portion 21 in the upper Hu. and the second bus bar 36 are stacked in the depth direction D, and the through hole 351 of the upper Hu of the first bus bar 35 and the through hole 361 of the second bus bar 36 are overlapped to be fixed to the terminal holding portion 21. Since the through hole 351 of the lower Hd of the 1 bus bar 35 and the through hole 333 of the wire side terminal 33 are overlapped and fixed to the terminal holding portion 21, the influence of the external force can be absorbed and the assembling property can be improved. can be done.

Specifically, inside the terminal holding portion 21, a flexible conductive member 32 having a tip connecting portion 321 connected to the wire connecting portion 312 of the female terminal 31, a wire-side terminal 33 and the flexible conductive member 32 are arranged. A connection fixing member 34 that is connected to the base end connection portion 322 and fixed to the terminal holding portion 21 is provided. The connecting fixing member 34 connects the flexible conductive member 32 to the first bus bar 35 having through holes 351 provided at both ends in the height direction H through which the fixing bolts 38 fixed to the terminal holding portions 21 are inserted. The second bus bar 36 is shorter than the first bus bar 35 in the longitudinal direction. That is, the base end connection portion 322 of the flexible conductive member 32 , which has the tip end connection portion 321 connected to the wire connection portion 312 of the female terminal 31 , is shorter than the first bus bar 35 in the longitudinal direction. is connected with Therefore, the flexible conductive member 32 and the second bus bar 36 connected to the female terminal 31 can be easily assembled to the terminal holding portion 21 .

The second bus bar 36 is provided with a through hole 361 fixed to the terminal holding portion 21 at the upper side Hu. and the through hole 361 of the second bus bar 36 are overlapped with each other and fixed to the terminal holding portion 21 . Therefore, the flexible conductive member 32 connected to the female terminal 31 can be fixed to the terminal holding portion 21 separately from the wire-side terminal 33 connected via the connection fixing member 34 .

Furthermore, the through hole 351 of the lower Hd of the first bus bar 35 and the through hole 333 of the wire side terminal 33 are overlapped and fixed to the terminal holding portion 21 with the fixing bolt 38 . Therefore, the wire-side terminal 33 and the wire harness 200 can be fixed to the terminal holding portion 21 separately from the flexible conductive member 32 connected to the female terminal 31 , and the female terminal 31 can be connected via the connection fixing member 34 . The flexible conductive material 32 connected to the terminal 31 can be electrically connected to the wire-side terminal 33 and the wire harness 200 .

In this manner, the female terminal 31 and the flexible conductive member 32, and the wire-side terminal 33 and the wire harness 200 can be independently attached to the terminal holding portion 21 and assembled. Therefore, the female terminal 31 and the flexible conductive member 32, and the wire-side terminal 33 and the wire harness 200 are easily attached and assembled to the terminal holding portion 21, respectively, and electrically connected via the first bus bar 35. can do. Therefore, the flexible conductive material 32 can absorb the influence of the external force, and the female terminal 31 and the flexible conductive material 32 can be easily assembled with the wire-side terminal 33 and the wire harness 200 to form the wire-side connector 20. Assemblability can be improved.
Further, since the first bus bar 35 can be fixed to the terminal holding portion 21 by the through holes 351 on both sides in the height direction H, a stable connection state can be maintained.

The through hole 351 of the first bus bar 35, which is fixed to the terminal holding portion 21 by overlapping the through hole 361 of the second bus bar 36, is arranged above Hu, and the through hole 351 below Hd of the first bus bar 35 is arranged. and the through hole 333 of the wire-side terminal 33 can be overlapped and fixed to the terminal holding portion 21 . Therefore, the wire-side connector 20 can be configured compactly without complicating the wiring route of the connecting fixing member 34 and the flexible conductive member 32 .

A base end connection portion 322 of the flexible conductive member 32 is connected to the lower portion Hd of the main surface 362 of the second bus bar 36 . Therefore, it is possible to prevent interference between the base end connection portion 322 connecting the second bus bar 36 and the flexible conductive member 32 and the fixing bolt 38 inserted through the through hole 361, thereby realizing a stable connection state. be able to.

In addition, the high-voltage electric wire 201 and the electric wire-side terminal 33 extend in the height direction H intersecting the female terminal 31 arranged along the depth direction D in the terminal holding portion 21, and the connection fixing member 34 extends in the height direction. H and the width direction W orthogonal to the depth direction D in which the female terminal 31 is arranged. Because it is connected to surface 362 , flexible conductive material 32 can be reliably connected to second bus bar 36 .

In addition, the terminal holding portion 21 often expands and contracts along the depth direction D due to heat. , an external force due to expansion/contraction or the like acts on the base end connecting portion 322 of the flexible conductive member 32 connected to the main surface 362 of the second bus bar 36 . As a result, the connection between the second bus bar 36 and the flexible conductive member 32 may become unstable.

On the other hand, since the main surface 362 of the second bus bar 36 to which the flexible conductive member 32 is connected faces the width direction W and the height direction H perpendicular to the depth direction D, the second bus bar 36 An external force due to expansion/contraction or the like is less likely to act on the base end connection portion 322 of the flexible conductive member 32 connected to the main surface 362 of the flexible conductive member 32, and a stable connection state can be maintained.

In addition, since the second bus bar 36 is laminated on the front side Df of the first bus bar 35 away from the female terminal 31 , the base end connecting portion of the flexible conductive member 32 connected to the female terminal 31 322 is connected to main surface 362 of second bus bar 36 so as to wrap around connection fixing member 34 . Therefore, compared with the case where the second bus bar 36 is arranged on the back side Db with respect to the first bus bar 35, the deformation margin following the expansion/contraction of the terminal holding portion 21 due to heat is increased, and the terminal holding portion 21 is deformed. When expanded and contracted, the flexible conductive material 32 is compactly deformed. Therefore, the wire-side connector 20 can be configured compactly.

In addition, since the through holes 333, 352, and 361 are fastened and fixed to the terminal holding portion 21 by the fixing bolts 38, the first bus bar 35 and the wire side terminal 33, and the second bus bar 36 and the first bus bar 35 are connected. By superimposing them and tightening them with fixing bolts 38 , they can be firmly fixed to the terminal holding portion 21 .
